This application claims priority from and the benefit of Chinese Patent Application No. CN202010638833.6, filed Jul. 6, 2020, the content of which is incorporated herein by reference.
The present invention relates to the field of tent accessories, and in particular to a tent peg and a processing method thereof.
The existing carbon composite material fiber tent pegs are mostly made of carbon fiber and aluminum materials which are generally formed by sticking metal components made of metal material such as aluminum or aluminum alloy onto both ends of the tube-shaped carbon fiber peg body. Such tent pegs have three defects. Firstly, when the adhesive is aged or overstressed, the metal components will easily fall off, making the product not durable. Secondly, the tube-shaped peg body does not have a hook-shaped point to fix ropes. If the ropes are tied on the tent pegs directly, they may easily slip off. Cord loops are generally used as hook points, and the rope must pass through the cord loops to be fixed, which is inconvenient to use. When users are wearing gloves on low temperature mountains, it will be difficult for them to let the ropes of the tent pass through the cord loops of the peg, and thus it is inconvenient to use on mountains. Thirdly, metal components made of aluminum or aluminum alloy can be easily damaged when impacting the rocks underground or struck by external forces, because the aluminum or aluminum alloy is low in rigidity. If it is simply replaced with a hard metal head made of steel, the weight will be significantly increased.
An object of the present invention is to overcome the defects of the prior art, and provide a lightweight, firm, durable and convenient tent peg. Another object of the present invention is to provide a method for processing a tent peg.

Furthermore, the peg head includes a bump, a pillar and a tip connected successively from top to bottom; the bump mates with the snap-fitting groove in shape and is disposed in the two snap-fitting grooves; the bottom end of the peg body is poured with the curing adhesive layer such that the adhesive is cured on a surface of the bump, increasing the volume thereof in order not to be able to slide out of the snap-fitting grooves. The tip is of a cone shape, and the pillar is of a cylinder shape.
Furthermore, both side surfaces of the bump are arc surfaces.
Furthermore, the peg cap includes a cap lid and a snap-fitting tube in a cylinder shape. The snap-fitting tube is mounted at a bottom end of the cap lid. A diameter of the cap lid is slightly greater than an outer diameter of the peg body. An outer diameter of the snap-fitting tube is slightly smaller than an inner diameter of the cavity of the peg body. A lower edge of the cap lid is closely adjacent to an upper edge of a wall of the peg body. A bottom end of the snap-fitting tube abuts against the second snap-fitting block in the cavity of the peg body.
Furthermore, the peg body is processed from a carbon fiber tube, the first and second anti-slipping hooks are cut from a carbon fiber sheet, and the peg cap and the peg head are made of hard alloy.
A method for processing a tent peg includes the following steps:
The principle of the present invention is that the peg body and the first anti-slipping hook and the second anti-slipping hook of the tent peg herein are made of carbon fiber material and the peg cap and the peg head are made of hard metal material. The weight of the tent peg can be greatly reduced, and the rigidity of the bottom and top of the tent peg can be significantly increased, enhancing the practicability, anti-striking and penetration ability of the tent peg. Mounting holes are provided at the top end of the peg body opposite to each other, and the first and second anti-slipping hooks and the peg cap can be fixed by snap-fitting with each other and pouring curing adhesive. The peg cap is closely adjacent to the upper edge of the peg body and the second anti-slipping hook, and the first and second anti-slipping hooks and the peg body are closely adjacent to each other. In this way, the pressure applied by the peg cap to the top edge of the peg boy can be shared, which can make the anti-slipping hooks stable and firm but also can enhance the resistance ability of the peg cap and the peg cap against vertical external force. By disposing snap-fitting grooves which are wide at the top and narrow at the bottom on both sides of the bottom end of the peg body, the shape of the bump of the peg head mates with the snap-fitting grooves, such that the peg head is fixed in the snap-fitting grooves firmly in the vertical direction, and by pouring the curing adhesive, the peg head can be connected integrally with the peg body.
The curing adhesive is preferred to be epoxy resin, because the carbon fiber per se contains epoxy resin, which can bond together firmly after curing epoxy resin and will not fall off easily. The curing adhesive not just acts as an adhesive, but also increases the volume of the first and second snap-fitting blocks and the bump after being poured and cured on the surfaces thereof, forming an anti-slipping structure and being snap-fitted firmly in the cavity of the peg body. Furthermore, the cured adhesive fills the gaps at the snap-fitting places, and has the effect of beautifying products.
Compared with the prior art, the present invention has advantages as below:
The tent peg in the present invention provides a new idea of providing anti-slipping hooks in the tube-shaped carbon fiber peg body. Mounting holes are provided on both sides of the top end of the peg body. The first and second anti-slipping hooks are snap-fitted with each other after being inserted into the peg body along the mounting holes on both sides of the peg body, and form a locking structure after the curing adhesive is poured and cured to increase the volume thereof, and is also integrally connected with the peg cap. Such a provision can share the pressure applied by the peg cap to the top edge of the peg body, which can not only improve the firmness between the first and second anti-slipping hooks and the peg body, but can also enhance the resistance ability of the peg cap against vertical external forces.
The unique connection structure of the peg head and the peg body can make the peg head of the tent peg herein sturdy and durable, not easy to fall off, significantly prolonging the service life of the peg. In common tubular carbon fiber and aluminum alloy tent pegs, a cylindrical metal head is simply adhered in the cavity of the peg body. The adhesive will be easily cracked or aged after long time of stressing, and the metal head is easy to fall off. Alternatively, when such a peg is inserted into hard ground, the metal head is stuck under the ground because of the pressure of the mud, and the adhesive layer may be easily damaged when the peg is forced to be pulled out of the ground, causing the metal head to fall off. In the peg according to the present invention, the bump can only slide into the peg body from the side, and the peg head cannot be pulled out of the snap-fitting grooves by forces in the vertical direction. Furthermore, the curing adhesive is integrally connected with the bump of the peg head in the peg body after being cured, increasing the volume of the bump, so that the bump is snap-fitted in the snap-fitting grooves at the bottom end of the peg body firmly and will not fall off easily.
The accompanying drawings constituting a part of the present invention are used to provide a further understanding of the present invention. Exemplary embodiments of the present invention and descriptions thereof are used to explain the present invention, and do not constitute an improper limitation of the present invention, in which:
The present invention is further described below in combination with the accompanying drawings and preferred embodiments.
As shown in
The peg body 2 is of a round tube shape with openings at both ends. The first anti-slipping hook 3, the second anti-slipping hook 4, the peg cap 1 and the peg head 5 are mounted on the peg body 2 through the mounting holes 6 and the snap-fitting grooves 7. The curing adhesive is poured at both ends of the cavity of the peg body 2, and undergo curing reaction at room temperature or after heating to be cured on surfaces of the first anti-slipping hook 3, the second anti-slipping hook 4, and the peg head 5 in the cavity of the peg body 2, increasing the volume thereof to form an anti-slipping structure which is connected integrally with the mounting holes 6 at the top end of the peg body 2 and the snap-fitting grooves 7 at the bottom end of the peg body 2 firmly, enhancing the firmness of the whole tent peg.
As shown in
The second anti-slipping hook 4 includes a second hook body 13, a second snap-fitting block 14, a second limit block 15 and a second hook claw 17. The second limit block 15 is disposed at an upper side of an end of the second hook body 13 close to the peg body 2. The second snap-fitting block 14 is disposed at a lower side of the second limit block 15. A second groove 16 corresponding to the second snap-fitting block 14 is provided at the end of the second hook body 13 close to the peg body 2. The second groove 16 is located at a lower side of the second snap-fitting block 14. The second snap-fitting block 14 contacts the first groove 11 of the first anti-slipping hook 3 after successively passing through the two mounting holes 6. The second groove 16 contacts the first snap-fitting block 9, such that the first anti-slipping hook 3 and the second anti-slipping hook 4 are snap-fitted with each other. An upper face of the second snap-fitting block 14 is closely adjacent to upper edges of the two mounting holes 6. A lower face of the second snap-fitting block 14 is closely adjacent to the first anti-slipping hook 3. The second limit block 15 abuts against the peg body 2 at the mounting hole 6 close thereto. The bottom end of the peg cap 1 abuts against the second snap-fitting block 14. The top end of the peg body 2 is poured with the curing adhesive layer 25 which is cured on surfaces of the second snap-fitting block 14 and the first snap-fitting block 9 in the cavity of the peg body, increasing the volume thereof to be greater than the opening of the mounting hole 6 in order not to be able to slide out of the mounting holes 6. The second hook claw 17 is mounted at an end of the second hook body 13 away from the peg body 2, and is oriented toward the peg body 2.
In this embodiment, the mounting hole is a square hole. In a specific implementation, four corners of the square hole can be rounded. The first hook body 8 and the second hook body 13 are in arc shape facing down, and used for fixing ropes. The length of the first snap-fitting block 9 and the second snap-fitting block 14 is greater than the outer diameter of the peg body 2, such that the two snap-fitting blocks can pass into a corresponding mounting holes and out of the other mounting hole completely to be snap-fitted with a corresponding groove. The width of the mounting hole 6 matches the width of the first snap-fitting block 9 and the second snap-fitting block 14. The height of the mounting hole matches the total height of the first snap-fitting block 9 and the second snap-fitting block 14. By means of such a provision, the first snap-fitting block 9 and the second snap-fitting block 14 will not rotate or slide after being inserted into the mounting holes 6. The volume of the first snap-fitting block 9 and the second snap-fitting block 14 in the cavity of the peg body 2 will increase after the curing adhesive (preferred to be epoxy resin) is poured and cured, while the size of the mounting hole 6 of the peg body 2 remain unchanged. Thus, the first anti-slipping hook 3 and the second anti-slipping hook 4 can be fixed on both sides of the peg body 2 firmly, and an external force applied to the two anti-slipping hooks can be shared with the edges of the mounting holes at both sides of the peg body, prolonging the service life of the tent peg while enhancing the firmness. The provision of the first limit block 10 and the second limit block 15 can prevent the first snap-fitting block 9 and the second snap-fitting block 14 from ceaselessly passing into the mounting holes, and make the protrusion distance of the two snap-fitting blocks mate with the length of the two grooves. The provision of the first hook claw 12 and the second hook claw 17 can prevent the ropes and the like from sliding out of the anti-slipping hooks when in use.
As shown in
As shown in
Both side surfaces of the bump 20 are arc surfaces, such that the bump 20 of the peg head 5 can form a complete cylindrical surface with the peg body 2 after being snapped into the snap-fitting groove 7. The tip 22 is of a cone shape. The pillar 21 is of a cylinder shape.
As shown in
The peg body 2 is processed from a carbon fiber tube. The first anti-slipping hook 3 and the second anti-slipping hook 4 are cut from a carbon fiber sheet. The peg cap 1 can be made of stainless steel or other hard alloy. The peg head 5 can be made of zinc alloy or other hard alloy. Such a provision makes the tent peg light (which only weights 6 g, 40% lighter than common lightweight tent pegs made of aluminum or titanium and other materials, and 80% lighter than common tent pegs made of iron), and also very firm and durable. Pure carbon fiber pegs or ordinary aluminum metal head pegs cannot be knocked directly on the top, nor can they be used in places with more frozen soil or sand. The peg herein can be knocked on the top with external force, and the peg head 5 has a higher hardness and can easily penetrate into frozen ground and sandy ground.
A method for processing a tent peg includes the following steps:
The processing of the tent peg disclosed herein is completed.
In the method for processing a tent peg, the order of disposing the peg cap, the first anti-slipping hook, the second anti-slipping hook and the peg head and the order of pouring the curing adhesive can be switched.
The curing adhesive in the processing method is preferred to be epoxy resin because of the characteristics of the carbon fiber material. The curing adhesive herein not just functions to adhere, but also increases the volume of the first snap-fitting block 9, the second snap-fitting block 14 and the bump 20 of the peg head 5 through its curing reaction, so as to be snap-fitted firmly to the peg body 2, enhancing the firmness of the whole tent peg.
Described above are preferred embodiments of the present invention, and are not intended to limit the present invention. Any changes or equivalent substitutions without departing from the technical solution of the present invention are all included in the protection scope of the present invention.
